Yup. It would only need 69% efficiency to deliver 50K with 415V supply voltage.

415V x 176A = 72K input
72K x 69% = 50K

The RMS rating is specified with 338V supply. 84% efficiency is not that unrealistic, especially with the higher voltage compared to a 12V amplifier. There would be less loss as heat.
338V x 176A = 59K
59K x 84% = 50K

Getting 415V supply voltage is the challenge. Not really that practical over a 18V or 24V system.

Thats hella power though.

i would like to see the guts of obne...i am gonna try to get some gut shots...
